Network Provisioning in SDN: Optimizing Network Resources for Enhanced Performance

Software defined Networking (SDN) provides a comprehensive view of the network and is good at handling changes in a traditional and simple network without needing a lot of updates. The purpose of this study was to determine the performance of SDN in various scenarios. However, the usual SDN architecture faced problems in handling bottlenecks. In our early research, we referred a lot of research papers for creating a model for a regular wired network with less nodes and traffic using standard SDN architecture. We developed the model using NetSim and observed the various network parameters such as overall throughput, delay and jitter. The recorded throughput exhibited a decrease, accompanied by increased delay and jitter, when assessing this basic network configuration. Later, we propose a new model with improved SDN performance, which resembles a normal wireless IoT network in real-time. The proposed model contains a novel priority and congestion control mechanism, called as ‘Updated SDN’, which has worked well in reducing network congestion especially in practical situations. It also maintains network's quality of service. The model provided results which had a significant improvement of 2% from the previous model. In Overall, our model looks at network delays and congestion at the SDN controller and delivers the packet properly with minimized loss. The results were analyzed by comparing the results of updated SDN and the standard SDN.
